Das System beinhaltet einen ersten Temperaturschalter, der auf dem Hochdrucktank befestigt ist und innerhalb eines Isoliergehäuses zum Überwachen der Temperatur innerhalb des Tanks eingeschlossen ist, und einen zweiten Temperaturschalter zum Überwachen der Temperatur des Wasserstoffgases an der Wiederbefüllaufnahme, wobei der zweite Temperaturschalter ebenfalls innerhalb eines Isoliergehäuses eingeschlossen ist. Falls die Temperatur innerhalb des Tanks über eine vorbestimmte Temperatur steigt, wird der erste Schalter schließen, und falls die Temperatur an der Wiederbefüllaufnahme unter eine vorbestimmte Temperatur fällt, dann wird der zweite Schalter schließen, was bewirkt, dass ein Aufwach-Signal an das Steuergerät geliefert wird, um dem Steuergerät das Überwachen der Temperatur des Tanks zu ermöglichen.A system is proposed for wake-up of a vehicle controller during a hydrogen gas refilling process for a high pressure hydrogen storage tank on a fuel cell vehicle. The system includes a first temperature switch mounted on the high pressure tank and enclosed within an insulating housing for monitoring the temperature within the tank, and a second temperature switch for monitoring the temperature of the hydrogen gas at the refill receptacle, the second temperature switch also being enclosed within an insulating housing is. If the temperature within the tank rises above a predetermined temperature, the first switch will close, and if the temperature at the refill receptacle falls below a predetermined temperature, then the second switch will close, causing a wake-up signal to be delivered to the controller to allow the controller to monitor the temperature of the tank.
Description
HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION
1. Gebiet der Erfindung1. Field of the invention
Diese Erfindung bezieht sich allgemein auf ein System und ein Verfahren zum Aufwachen (Wake-Up) eines Steuergeräts während eines Wiederbefüllprozesses eines Wasserstoffgasspeichertanks und insbesondere auf ein System und ein Verfahren zum Aufwachen eines Steuergerätes während eines Wiederbefüllprozesses von einem Wasserstoffgasspeichertank durch Überwachen der Temperatur des Speichertanks und der Temperatur des Wasserstoffgases am Wiederbefülleinlass, wenn das Steuergerät gerade abgeschaltet wurde, um Batteriestrom zu sparen.This invention relates generally to a system and method for wake-up of a controller during a refilling process of a hydrogen gas storage tank, and more particularly to a system and method for waking up a controller during a refilling process from a hydrogen gas storage tank by monitoring the temperature of the storage tank and the temperature of the hydrogen gas at the refill inlet when the controller has just been shut down to conserve battery power.
2. Diskussion des Standes der Technik2. Discussion of the Related Art
Wasserstoff ist ein sehr attraktiver Brennstoff, da er sauber ist und dazu verwendet werden kann, effizient Elektrizität in einer Brennstoffzelle zu produzieren. Die Automobilindustrie wendet signifikante Ressourcen in der Entwicklung von Wasserstoffbrennstoffzellensystemen als eine Antriebsquelle für Fahrzeuge auf. Solche Fahrzeuge wären effizienter und würden weniger Emissionen als heutige Fahrzeuge erzeugen, die eine Verbrennungskraftmaschine verwenden.Hydrogen is a very attractive fuel because it is clean and can be used to efficiently produce electricity in a fuel cell. The automotive industry uses significant resources in the development of hydrogen fuel cell systems as a vehicle power source. Such vehicles would be more efficient and produce fewer emissions than today's vehicles using an internal combustion engine.
Typischerweise wird Wasserstoffgas für ein Brennstoffzellensystem unter hohem Druck in einem Tanksystem gespeichert, das einen oder mehrere miteinander verbundene Druckkessel auf dem Fahrzeug bereitstellt, um das Wasserstoffgas, das notwendig ist, für den Brennstoffzellensystem bereitzustellen. Der Druck innerhalb der Kessel kann 700 bar oder mehr betragen. In einer bekannten Ausführungsform beinhalten die Druckkessel eine innere Plastikbeschichtung, die eine gasdichte Abdichtung für das Wasserstoffgas bereitstellt, und eine äußere aus Karbonfiber-Verbundmaterial bestehende Schicht, die die strukturelle Integrität des Kessels liefert. Da Wasserstoffgas ein sehr leichtes und diffuses Gas ist, müssen die innere Auskleidung und die Tankverbindungskomponenten sorgfältig konstruiert sein, um Lecks zu vermeiden. Das Wasserstoffgas wird aus dem Tank über eine Leitung entfernt. Zumindest ein Druckregler ist typischerweise vorgesehen, der den Druck des Wasserstoffgases innerhalb des Tanks auf einen geeigneten Druck für das Brennstoffzellensystem reduziert.Typically, hydrogen gas for a high pressure fuel cell system is stored in a tank system that provides one or more interconnected pressure vessels on the vehicle to provide the hydrogen gas that is necessary for the fuel cell system. The pressure inside the boiler can be 700 bar or more. In one known embodiment, the pressure vessels include an inner plastic coating that provides a gas-tight seal for the hydrogen gas, and an outer layer of carbon fiber composite that provides the structural integrity of the boiler. Since hydrogen gas is a very light and diffused gas, the inner liner and tank connection components must be carefully designed to prevent leaks. The hydrogen gas is removed from the tank via a pipe. At least one pressure regulator is typically provided which reduces the pressure of the hydrogen gas within the tank to an appropriate pressure for the fuel cell system.
Die Wasserstoffgasspeichertanks auf Brennstoffzellenfahrzeugen werden an einer geeigneten Wiederbefüllstation wiederbefüllt, wobei geeignete Aufnahmen, Leitungen, Ventile etc. bereitgestellt sind, um die Tanks an eine größere Wasserstoffgasquelle zu koppeln. Diese Arten von Wiederbefüllstationen sind oft in der Lage, die Wasserstoffgasspeichertanks auf dem Fahrzeug sehr schnell wieder zu befüllen, indem ein schneller Wasserstoffgasfluss bei einem signifikant höheren Druck bereitgestellt wird. Falls der Wasserstoffgasspeichertank nahezu leer ist und einen niedrigen Druck aufweist, wird das schnell fließende Wasserstoffgas, das in den Tank eintritt, schnell expandieren und dabei ein signifikantes und schnelles Anwachsen der Temperatur verursachen. Typischerweise wird die Temperatur innerhalb des Tanks nicht signifikant anwachsen, wenn ein genügend hoher Druck innerhalb des Tanks während des Wiederbefüllprozesses herrscht. Da die innere Auskleidung des Tanks, die eine Gasdichte Abdichtung bereitstellt, ein Polymer ist, haben hohe Temperaturen innerhalb des Tanks einen Alterungseffekt auf die Auskleidung, welche letztendlich mit der Zeit und der Zahl von Wiederbefüllereignissen zu einem Verlust an der Abdichtungsintegrität führen könnte. Da dies ein Problem darstellt, ist es aus dem Stand der Technik bekannt, einen Temperatursensor auf dem Tank bereitzustellen, der die Temperatur des Wasserstoffgases während des Wiederbefüllereignisses überwacht, wobei die Temperaturen während des Wiederbefüllens über die Zeit aufgezeichnet werden. Ein Algorithmus ist bereitgestellt, um die stabile Lebenszeit der Auskleidung basierend auf der Information, wie oft die Temperatur eine vorbestimmte Temperatur und für wie lang die Temperatur eine vorbestimmte Temperatur überschreitet, zu bestimmen.The hydrogen gas storage tanks on fuel cell vehicles are refilled at a suitable refilling station, with appropriate receptacles, lines, valves, etc. provided to couple the tanks to a larger source of hydrogen gas. These types of refill stations often are able to refill the hydrogen gas storage tanks on the vehicle very quickly by providing a fast flow of hydrogen gas at a significantly higher pressure. If the hydrogen gas storage tank is nearly empty and has a low pressure, the fast-flowing hydrogen gas entering the tank will expand rapidly, causing a significant and rapid increase in temperature. Typically, the temperature within the tank will not increase significantly if there is a sufficiently high pressure within the tank during the refilling process. Because the inner liner of the tank that provides a gas tight seal is a polymer, high temperatures within the tank have a lining aging effect that could eventually lead to a loss of seal integrity with time and number of refill events. Since this is a problem, it is known in the art to provide a temperature sensor on the tank that monitors the temperature of the hydrogen gas during the refill event, with temperatures recorded during refilling over time. An algorithm is provided to determine the stable lifetime of the liner based on the information of how often the temperature exceeds a predetermined temperature and for how long the temperature exceeds a predetermined temperature.
Einige Wiederbefüllstationen sind SAE-zertifiziert und empfangen Kommunikationssignale von dem Fahrzeug während des Wiederbefüllprozesses. Bei SAE-zertifizierte Wiederbefüllstationen werden die verschiedenen Temperatur- und Drucksignale von dem Fahrzeug observiert. Andere Wiederbefüllstationen sind nicht SAE-zertifiziert, wobei das Fahrzeug unabhängig die Temperatur des Tanks während des Wiederbefüllprozesses unter Verwendung des Temperatursensors überwachen muss.Some refill stations are SAE certified and receive communication signals from the vehicle during the refill process. At SAE-certified refill stations, the various temperature and pressure signals are monitored by the vehicle. Other refill stations are not SAE certified and the vehicle must independently monitor the temperature of the tank during the refilling process using the temperature sensor.
In einer bekannten Brennstoffzellensystemausgestaltung weist die Wiederbefülltür oder -klappe, die während des Wiederbefüllprozesses geöffnet ist, um die Wiederbefüllaufnahme freizulegen, die mit der Wiederbefüllstation verbunden ist, einen Schalter auf, der geschlossen ist, wenn die Klappe offen ist, um ein Signal an das Fahrzeugsteuergerät zu liefern, das ein Wiederbefüllereignis am Beginnen ist. Falls das Fahrzeug ausgeschaltet ist, wird das Steuergerät aufwachen, sobald der Schalter geschlossen ist in Erwartung, dass das Wiederbefüllen bald die Aufzeichnung der Temperatursignale von dem Temperatursensor erfordern wird, sobald der Fluss von Wasserstoffgas zu dem Tank überwacht wird. Ferner findet eine Überwachung des Tankdrucks und der Wasserstoffkonzentration statt. In einigen Situationen kann der Fahrzeugführer die Wiederbefüllklappe öffnen, aber nicht sofort mit dem Wiederbefüllprozess beginnen. Da der Batterieladezustand einer Niedervoltbatterie auf dem Fahrzeug eine begrenzte Ladung aufweist und nicht wiederaufgeladen wird, wenn das Fahrzeug ausgeschaltet ist, sind Algorithmen bereitgestellt, um die Abgabe von Batteriestrom zu reduzieren oder zu steuern. In einer Ausführungsform bleibt das Steuergerät, das den Klappenschalter überwacht, nur im aufgebrachten Zustand für eine gewisse Zeit nachdem der Schalter geschlossen wurde und wenn der Wiederbefüllprozess während dieser Zeit nicht initiiert wird, wird das Steuergerät abgeschaltet, um Batteriestrom zu sparen, auch wenn der Klappenschalter geschlossen ist. Wenn der Fahrzeugführer dann den Wiederbefüllprozess ausführt, nachdem das Steuergerät ausgeschaltet wurde, wird das Steuergerät nicht in der Lage sein, die Temperatur und den Druck während des Wiederbefüllereignisses zu überwachen, was Konsequenzen für die Bestimmung der nutzbaren Lebensdauer des Tanks haben könnte.In a known fuel cell system configuration, the refill door or flap, which is open during the refill process to expose the refill receptacle connected to the refill station, has a switch that is closed when the flap is open to send a signal to the vehicle controller to deliver, which is a refill event at the beginning. If the vehicle is off, the controller will wake up as soon as the switch is closed in anticipation that the refilling will soon require the recording of the temperature signals from the temperature sensor as soon as the flow of hydrogen gas to the tank is monitored. Furthermore, a monitoring of the tank pressure and the hydrogen concentration takes place. In some situations, the driver may be the Open the refill flap, but do not immediately start the refill process. Because the battery state of charge of a low voltage battery on the vehicle has a limited charge and is not recharged when the vehicle is off, algorithms are provided to reduce or control the delivery of battery power. In one embodiment, the controller that monitors the flap switch remains in the on-state for a period of time after the switch has been closed, and if the refill process is not initiated during that time, the controller is turned off to conserve battery power even if the flap switch closed is. If the driver then performs the refill process after the controller has been turned off, the controller will not be able to monitor the temperature and pressure during the refill event, which could have consequences for determining the useful life of the tank.
